Referring to the drawings, the numeral 1 is used to designate in general a supporting frame-work. A shook carrier designated in general by the numeral 2 is mounted upon the upper portion of the frame-work 1, said carrier comprising a pair of parallel endless conveyor chains mounted over sprockets 3 carried by shafts 1 and 6 extending trans-' versely across the frame adjacent the ends thereof. The sprockets3 upon'the driv ng end of the carrier are feathered onto the shaft 4 by means of a suitable key-way 7 while the sprockets 3 atjthe opposite end of the-carrier are both rotatably and slidably movable upon the shaft 6., Each chain 2 is provided with a plurality of shook engaging lugs 8 arranged at regularly spaced intervals,- the lugs of the chains, being arrangedin matching relation.

1 The carrier '2 is actuated by means of a suitable, source; of power, such as an electric motor 9 mounted upon a bracket 11 upon the lower portion of the frame 1. The motor 9 .is pi'ovidedwith a pulley '12 to receive a belt 13 connected over a pulley 14 secured upon a shaft: 16 mounted transversely across the frame 1 adjacent the driving end of the carrier. The shaft 16 is provided with a pinion 17, meshing with a gear18 mounted upon a "shaft 19-extending transversely across the frame 1. The gear 18 has a pinion 21 secured in connection therewith and meshing witha gear 22 secured upon the shaft 4, the

' gears and pinions being designed to obtain a proper reduction of speed between the motor and the carrier drivlng shaft 1-. The gears 18 v and 22 are mountedupon the outer side of the framework and are preferably covered by suitable guards 23 and 24:.

i A suitableshook holder designated in gen-- eral by the numeral 26 is mounted upon the frame 1 above one end of the carrier 2. The holder 26 is arranged to receive a supply of shocks, or box ends 27 stacked therein and arranged to be delivered from the bottom of the holder. The stack of shooks is supported upon a pair of rails 28 with the lowermost shook 27 just clearing the upper surfaces of the carrier chains 2, as best shown in Fig. 21 of the drawings.

Detents are mounted adjacent the bottom of the holder 26 upon the forward side thereof, each detent comprising a roller 29 mounted upon a' slidable member 31 actuated by a spring 32 to normally hold the roller in a position opposite the forward edges of the two lowermost shooks. The axis of each roller 29 is opposite the edge of the shook next to the bottom, and the lower edge of the roller normally extends slightly below the upper edge of the lowermost shook. The lugs 8 extend upwardly from the chains 2 sufiiciently to engage the rearward edge of the lowermost shook. .As the carrier is operated, the pairs of lugs 8 are moved against the rearward edge of the then lowermost shook and force said shook forwardly from under the stack of shooks, the rollers 29 being forced upwardly against the pressure of the springs 32 sufficiently to permit the movement of the lowermost shook thereunder while still operating to hold the second shook against forward movement. Asthe lowermost shook is moved from under. the stack, the remaining shocks drop down onto the rails 28 in position for the then lowermost shook to be engaged and moved forwardly by the next approaching pair of lugs 8. The supply of shooks in the holder 26 is maintained automatically or by hand as desired.

The sprockets 3, over which the carrier 2 operates, are adjustable longitudinally of the shafts 4* and .6 by means of adjusting members 33 mounted upon shafts 34 and 34' extending transversely across the frame 1 in spaced parallel relation to the shafts 4 and 6. The shafts 34 and 34: are each provided with right and lefthand threads upon opposite ends thereof, said threads engaging the adjusting member whereby a rotation of the shafts 34 and 3loperate to move the adjustoperates to adjust the spacing of the sprockets 3 upon each shaft 4: and 6 to accommodate various widths of shooks 27. A chain 35 is connected over sprockets 35 secured upon the shafts and 34 whereby the shafts may be rotated simultaneously by means of a suitvable crank 35 mounted upon one of said shafts.

Carrierguides 37 are connected at their ends to the adjusting member 33 at opposite ends of the frame 1. [The guides 37 are angular in form with upwardly extending flanges formedupon their outer edges to r form guides for the sides of the shocks, the guides beingadpisted with themembers 33 t accommodate various widths of shoo is.

The guides 3? are provided with tracks 38 en.-

gaged by the rollers 2 ofthev carrier chains 2 to support the links 2-" of said chainsclear from the guides 37, as best shown in Fig. 2 1

of the drawings, whereby the weight of the chains and the shocks 2'? carried thereon together with downwardpressure applied upon the shocks, is carried by the rollers thereby. preventing wear upon' the llIlliS, and reduc ing thefrictional resistance tomovement of I A brush 39 is mounted transverselyacross" I i the top of the frame 1 immediately forward .lation to the brush 39;v

from the shook holder 26, the bristles of said brush being arranged to sweep the surface 7 of the shocks 27as said shocks are moved forwardly fromtho holder. The brush is partially enclosed by a housing 40 and is driven by means of a belt/11 connected over pulleys 42 and i3 mounted upon the outer endsof the brush-shaft and the shaft 16 respectively.

A roller 44 is mountedtransversely across the top of the frame 1 in spaced parallel 1'67 The rollerisprovided witha pad 46 of'dfesired size a'nd shape, secured upon the surface of the roller 4 41- and arranged to form a rolling contact with the surface of each shook moved thereunder by the carrier 2'.

A suitable adhe'ive material is appliedby the pad 16 onto the surface'of each succes-.

sive shook, said adhesive material being supplied from a trough 47 extending transverse ly across the frame 1. hieueras is rotatably mounted within the trough and arranged to dip into the adhesive material contained therein. A roller 19 rotatably mounted in proximate relation toth'e roller 48- serves to displace'surplus adhesive material picked up by the roller 48. A roller 51 rotatablymonnted in proximate contacting relation to the roller 18 and the surface ofthe pads-6 'op-'.

erates to transfer adhesive material from said roller 48 onto the pad 46;

The pad 46 is cemented or otherwisesecured'to the roller 44: wherebythe pad may be removed and pad of different size substituted when desired, the size o f the pad being designed to conform tothe size of the label'to be applied whereby adhesive will be appliedby said pad ontothe shocks-27 to cover only that portion of the shooks to'whieh A label holder, designated in A 2 to receive a supply of labels 53. The labels 53 are supported edgewise within the holder and are inclined only slightly from a Vertical position,'said labels being pressed against a retaining member 5-: by a movable member The labels are supported upon slats a-hollow shaft 57 mounted transversely across the'machine immediately in back of the retaining member V Thefeedingamember 56 is preferablyyokeshaped and provided with a pairof spaced parallel arm portions 56 having suction passages 58 therein and also having suction 'openings 59 formed in the ends thereof. The I passages 58 communicate with the interior of the hollow shaft 57.1 The shaft 57 is mountedupon the upper ends of a pair of arms 61 pivoted by means ofbearing portions 62 upon opposite sides of the machine at points alinedwith the lower edge of-the retaining member; 54:. One of the pivots 62 is provided with alateral extension 63 engaged by a cam 64 secured'upon a shaft 65 extendin transversel across the frame 1 said extension being held in engagement with.

said cam by means of a' spring 68. The cam 6a is provided .witha portion 67 arranged to move the extension 63. against the tension of the spring 66' thereby imparting an oscillat- 1 ing pivotal movement to the arms 61 and to the feeding member 56.

The-hollow shaft'57 is provided with a. V

flexible connection 68 connected thereto and communicating with the hollow interior of the shaft. The connection 68 is connected to a suction pipe 69 which in turn is connected v p e to the suct onrslde of a su table pump 71,,or

other source of suction. The pump is actuate ed by means of a belt 72dri'ven by the motor 9. The suction pipe 69- is provided with a suitable valve 73 operable to open and close theconnection. to theshaft 57 and feeding member 56, said valve being normally closed and'being providedwith a stem ,74 arranger to be engaged by acam 76 mounted upon the shaft'65 for moving said valve to open position during a portion of eachrevolution or the'shaft 65, as hereinaftermore fully explained.

The shaft 65' is provided with a plurality T ofdrums 77 secured in spaced relation upon said shaft. A gripper shaft 78 is rotatably mounted through the dru1ns77 in spaced relationto the shaft 85. A gripper arm 7 9 is secured'upontheshaft 78 within each drum,

said arms 79 being movable from an inooc. l

er ative position within the drums tofl'operative positions extending outwardly through c e a by the numeral 52, 1s mounted'above the carrier openingsSl formedin thefperipheries of the cured upon the shaft adjacent one endtrip 83 is mounted upon the end thereof. A of the shaft adjacent the outer side of the disc 82, and a lever 8 1 18 secured upon the shaft 78 adjacent the inner side of said disc 82. A spring 86 is mounted upon a guide rod 87 pivot-ally connected to the lever 8 1 and slidably and pivotally engaging a guide 88 secured to the disc 82 the spring being an ranged to be compressed to impart a quick throw to the lever 84 and shaft 7 8 to either extreme. position when the lever 8st passes the mid-point of its movement in either direction.

Thetrip 83 is provided with an outwardly disposed flange 83 having outwardly inclined portions formed at its ends. Pins 89 and 90 are rigidly secured upon a plate 91 secured to the frame 1 of the machine. The pins 89 and 90 are positioned in such manner that as the gripper shaft 78 is revolved around the shaft 65 with the drums 77 the flange 83 will engage the pins alternately. As the trip 83 is moved toward the pin 89, as indicated in Fig. 10, the flange 83 is moved against the pin. The further movement of the disc '82 with the shaft 65 and shaft 78 causes the trip 83 to rotate said shaft 78 relative to the drums 77 and disc 82 until the flange of said trip is swung to the inside of the pin 89. As the lever 84 passes the line between the axis of the shaft 78 and the guide 88, the spring 86 imparts a quick throw to the shaft 78, thereby carrying the flange 83" inwardly to clear thep'in' 89-and at the same time rotating the shaft 78 sufficiently tomove the gripper arms 7 9 from their in-.

operative positions as shown in Fig. 8 to an operative position as shown in Fig. 11.

While the trip 83 occupies its inwardly turned position'as shown in Figs. 13 and 18, the rotation of the shaft causes the trip to be moved into contact with the pin which is so positioned that as the end of the shaft 78 is carried past the pin 90., the trip will engage said pin 90 and the flange 83 will be turned to the outside,as shown in F 15. As the lever 84- is moved past its center of movement tlic 'spring 86 is compressed to impart a quick throw carrying the lever and shaft 78 to its opposite extreme position with the grippingarms 79 again moved to inoperative position within the drums 77. The pins 89 and 90 are so positioned relative to the of the shaft 65 that the lange 83 is moved to pass upon i he inside of the pin 89 and upon the outside of the pin 90 and said pins are so spaced from each other as to move the gripping arms 79 to operative and inoperative positions through substantially 180 of rotation of the shaft 65;

A label applying roller 91 is mounted roller to cominunicate with the hollow intenor of the roller.

The suction connection 92 is connected to the suction pump 71, preferably by connecting said connection 92 into the suction pipe 69 at a point between the valve 73 and the pump. The connection 92 is provided with a check valve 92 normally closing said connection and being operable by suction to open said connection when the valve 73 is closed or when the suction openings59 of the feeding member 56 are closed by a label when the valve 73 is open. The connection 92 is also provided with a suction relief valve 9 1 having a valve member 95 normally seated to close a port 96 opening outwardly to the atmosphere. The valve member 95' is provided with a stem 97 arranged to be engaged by a cam 98 mounted upon the shaft 65 adjacent the cam 76 to open said port and relieve the suction within the hollow roller 92 and thereby release a label onto a passing shook 27 as hereinafter more fully explained.

The. drums 77 and the roller 91 are made of the same diameter andthe roller 14: in-

cludingthe pad 46 thereon is also made of the same diameter,'said diameter being such that the circumference of said drums and rollers will equal the space between the lugs 8 along the carrier chains 2 whereby a complete revolution of the drums and rollers will bring the same points thereof into corresponding position relative to each shook 27 as said sliooks are moved successiv ly therepast by the carrier.

The rollers 91 and 4a and the shaft 65 car- 107 mounted upon an outwardly disposed extension 108 of the applying roller 91, and an idler sprocket 109 is mounted upon a slidably adjustable support 111 for adjusting the tension of the chain 101. The sprocket 102 is driven by the carrier drive shaft 4, said sprocket preferably being rotatably mounted upon the outwardly disposed extension of the shaft 341. The sprocket 102 is secured in connection with a gear 112 meshing with a similar gear 113 secured upon said shaft 41.

As the-shook 27 is moved forwardly, the

brush 39 operates to sweep the uppersur.

The shook27 'i's plying roller and at the same time, the next pair of lugs 8 engage and move the neXt'succee' ding shook forwardly toward the brush 39 and roller 44. I

As the first, and each successive shook 27,

wardly under the roller 44with its pad 46 .85 rotation" of the roller as'the shook 27 is.

is'movedforwardly past the brush 39, the shook engages a trip lever 137 pivotally mounted below the upper course of the car-' rier 2. The shook 27 is held down bya roller I .138, therebycausing the .trip 137 tobe de pressed to actuate a lever 139 against the normal tensionof a spring 141*, the lever 139 being mounted upon the shaft 142 upon which the trip lever l37 is secured: The

lever 139 in turn actuates a link 143 connectedto a bell crank 144 mounted adjacent thecam76 secured upon the shaft 65. A wedge member 147 is pivotally mounted'upon the crank 144 and is arranged to be moved by said crank to an operative position between the cam 7 6 and the stem 74 of-the 'valve73. p 3 Theo-perationof. the'trip' 137 "and wedge member 147 is illustrated in Figures 24,25, A

and 26 of the drawings. Thus, when the' trip lever1'37is in its normal ralsed pos1t1on,

the wedge member 147 is elevated to a position such that the thin lower end of the wedge is'interposed between the'cam76 and the stem 74, asshown' in Fig. 24. While in this position the rotation of the cam 76 through its operativeiphasm as shown in Fig. I

25 does not displace the wedgemember sufficiently to engage the valve stem 74 and'th'e Valve 73 therefore remains in its normal closed position. \Vhen the trip lever'137 is depressed by alshook'27, thewe'dge member is moved downwardly to 'interpose its thick section between the; earn 7 (Sand the stem 74,

whereby movement of the cam throughits faces of the drums arms operative phase, as shown in Fig. 26, causes said wedge member to be moved against the stem 74 and. thereby open said valve While the high portionof the cam passes the wedge member. The shaft 142 is provided with a lever 1 18 whereby the trip 137 may be operated manually independently of a shook if desired. 1

As the shook 27 actuates the trip lever 137 and opens the valve 73, as above described, the cam 64 carried by the shaft 65 is moved to cause the extension 63 to be moved to the position shown in Figs. 9 and 27 of the drawings, thereby swinging the arms 61 upon their pivots 62 and moving the label feeding member 56 to the position shown in full lines in Figs. 9 and 27 of the drawings. This movement of the feeding member 56 causes the ends of the'arm portions thereof to engage the label 53 immediately back of the retaining member upon the portion immediately below the lower edge of said retaining member, the suction openings 59 being moved immediately against said label.

When the valve 73 is open, suction from V the pump 71 operate through the suction pipe 69 and flexible connection 68 to draw and hold the adjacent label against the ends of the arm portions of the feeding member. As the shaft 65 is further rotated, the extension 63 is moved back from the high point of the cam 64 to its normal position by the spring 66, thereby returning the feeding member to the position shown in dotted lines in Fig. 27 andin full lines in Figs. 11, 14, 17, and 22, whereby the edge of the label held thereon by suction is moved against the sur- 77 as shown in Figs; 7, 11, and 22.

While the edge ofthe label 53 is held against the drums 77, the rotation of the shaft 65 ,andd'rums 77 causes the trip 83 to engage the pin 89 and to swing said trip from the relative position shown in Fig.

; to the position shown in Fig. 13 and thereby rotate the shaft 78 and move the gripper arms 79 from inoperative position as shown in F ig. 8 to operative gripping position as shown in Figs. 11 and 22. The endsof the gripper arms 79 move to grip the edge of the label against the surface of the drum. A gripping pin 151 is preferably slidably movable through an opening 152 formed in the periphery of each drum 77 and actuated by a spring 153 within the drum to normally extend slightly outwardly from the drum in a position to be engaged by the gripping arms when moved to gripping position. The outwardly extending ends of the pins 151 are knurled to cooperate with the gripping to insure an efiicient gripping of the labels. As the rotation of the shaft and drums 77 is continued, the label is drawn away. from the feeding member 56 and pulled from the holder 52, said label being rolled onto the drums as said drums are" rotated. i

'As the edgeof the label 53 is moved between theproximate surfaces of the drums 77 and the applying roller 91, the trip 83 is moved to engage the pin 90 whereby the trip is caused to turn the shaft 78 and move the gripping arms 79 to release the label, as

shown in Fig. 14. "The suction openings 93 of the roller 91 are arranged to be moved into contact with the label carried by the drums 77 at the moment the label is released by the gripper arms 79, the suction from the pump 71, operating past the check valve 92, causing the edge of the label to be held onto the roller 91 and to be carried over said roller as shown in various positions in Figs. 8, 11, and 17. Guards 149 are mounted concentrically with the roller 91 and in spaced relation to the upper portion thereof to direct the label away from the drums 77 and around the roller 91, should the label become disengaged from the roller 91 by an inadvertent breaking of the suction in the roller.

The roller 91 reaches the position shown in Fig. 17 as the shook 27 is moved thereunder so that the label 53' is rolled onto the portion of the shook which has been rendered adhesive by contact with the pad 46. At the instant the forward edge of the label contacts with the shook, the relief valve 96, is opened to relieve the suction within the roller 91, the cam 98 being timedto engage the stem 97 and actuate the valve member 95 and thereby open the port 96 in timed relation to the rotation of the roller 91. The label being thus released from the roller 91 is laid smoothly onto the shook and'is carried forwardly by the shook to the rollers 121. The rollers 121 operate to press the label firmly onto the shook.

The labelled shook is then carried forwardly over the end of the carrier 2 and is received upon the rails 126 as indicated in dotted lines in Fig. 2. The member 127 is then moved as above described to force the shook forwardly along the chute 124:, as indicated in dotted lines in Fig. 2.

The label feeding and applying mechanism isactuated in timed relation to the movement of the carrier so that a label is fed and applied upon each successive shook. In event a shook is not fed to the carrier, the trip 137 is .not actuated and the valve 73 will not be opened. In this event, no suction will be applied through the feeding member 56 to engage a label from the supply contained in the holder 52 and hence no label will be fed onto the drums 7 7 and applying roller 91.

The check valve 90 operates to normally close theconnection to the roller 91. In starting the machine, when no label is being carried by the roller 91, the openings 93 would permit an intake of air such that no appreciable suction would be present in the feeding member 56 to engage and feed a label.

The check valve 92'soperates to close the connection to the roller 91 until the suction through the pipe 69 exceeds the spring resistance of the check valve. Thus, when the,

valve .73 is opened and'the arms-of the feed r 2 1 1 mg member 06 are moved to pick up a label, the openings 59 are ciosed by said label and the resulting suctionwill operate'to' unseat the check valve and obtain a suction in the roller 91. When the relief valve94 is opened, the check valve 92 again operates to close the connection and insure suction to the feeding member to engage and feed the next label.

The area of each shook to Which'the adhesive is applied is varied according to the sizeof the label by correspondingly varying the moving said sprocket to permit the chain 101 to be removed from theseveral sprockets driven'thereby. The carrier 2 is the11,ad-.

vanced. or receded the desired amount ithout altering the timingof the roller 44 and said label feeding and applyingmeans. The chain 101 isfthen replaced 1n operative engagement with theseveral sprockets. As this change in ad ustment may cause the chain 101 tobe movedout of 1116sh with the sprocket 103 driving the shaft 65, said sprocket is provided With slots 154 engaged byfsecuring members 155' whereby the sprocket may be adjusted, relative to the shaft 65, to mesh With the chain Without alter ingthe timing ofthe shaft 65. As the label feeding. and applying mechanism is timed *With respect to the forward edge of'the'labels fed, the carrier 2 may be adjusted so that the edge of each label will be placed at a uniform distance from the foremost edge. of each shook, thus insuring: anf'eflicient' operation with various sizes of shooks and labels. The

shaft 16 is provided With a hand Wheel 157,

whereby the machine may be operated man ually for making adjustments.

Thesuction feeding arms; operate to efficiently separate the labels singly fromthe supply, and the gripping means operates to Withdraw said labels from the supply and to transfer the same onto the applying roller Without subjecting the labels to excessive strain and with'out marring or disfiguring the labels in any Way.

The carrier 2 together with the guides 37 may be quickly and efiiciently adjusted to accommodate shooks of various idths. justing means 156 are, also provided in connection With the rollers 44, 9,1. and shaft v65.

whereb-y the same may be adjusted to accommodate shooks of various thickness portions of the shooks. I w
